Challenge Problems
Push your limits with challenges.
Question 1
Design a scenario in which an RLC circuit's impedance must be optimized for a specific frequency. Include calculations for R, L, C, and the resulting Z.
π‘ Hint: Use the impedance formula and plug in your chosen target frequency into the equations.
Question 2
Explore a mechanical system with given mass and damping. Determine how changing the mass affects mechanical impedance at various frequencies.
π‘ Hint: Changing the mass will affect the k-mΟΒ² term. Keep this in mind as you plug values into Zm.
